Update git submodules

* Update docs/submodules/yardstick from branch 'stable/euphrates'
  - Merge "NSB TRex: convert DPDK port number to logical TRex port number" into stable/euphrates
  - NSB TRex: convert DPDK port number to logical TRex port number
    
    when we create TRex config we sort based on PCI bus address
    and create a logical port ordering.
    
    We need to save this port ordering and re-use it everywhere.
    
    redirect vnfd_helper.port_num() to resource_helper.port_num() to
    use the logical mapping
